Use this table as a prompt until you are confident with the method. Therefore, the molar mass of sulfur dioxide is 1 × 32.1 + 2 × 16.0 64.1 g/mol. Example 1: Calculating the relative molecular mass of CH4. If you look back at the formula ( SO2 ), you can see that there is one sulfur and two oxygens present. The molar mass of sulfur is 32.1 g/mol, and oxygen is 16.0 g/mol.
